We look at the division of 15074492 by 451 
The aim is to understand the frequency of 451 in 15074492.

Moving on to step 1:
The number 451 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 451

Going ahead to step 2:
When dividing 15 by 451, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 451

Step 3:
If we divide 150 by 451, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 150, we get 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 451

Advancing to step 4:
1507 divided by 451 is 3 with a remainder of 154.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1353 from 1507 leaves us with 154.
Bring next digit (4) of the dividend behind the 154 and repeat the process: 1544 / 451

Let's proceed to step 5:
451 can be fit into 1544 3 times, resulting in a remainder of 191.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 1353 from 1544, we get 191.
Fetch the next digit (4) from the dividend, attach it to 191 and continue: 1914 / 451

On to step 6:
The number 451 fits into 1914 4 times, leaving a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 334.0
If we take 1804 away from 1914, we end up with 110.
Include the next digit (9) from the dividend after 110, then repeat: 1109 / 451

Advancing to step 7:
1109 divided by 451 is 2 with a remainder of 207.
Record the quotient 2 as the next digit in the result. 
Result so far: 3342.0
Subtract 902 from 1109 to get 207.
Bring next digit (2) of the dividend behind the 207 and repeat the process: 2072 / 451

On to step 8:
The number 451 fits into 2072 4 times, leaving a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 33424.0
Subtracting 1804 from 2072 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 9:
The number 451 fits into 2680 5 times, leaving a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 33424.5
Deduct 2255 from 2680 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 10:
The number 451 fits into 4250 9 times, leaving a remainder of 191.
The number 9 becomes the next digit in our result. 
Result so far: 33424.59
Subtracting 4059 from 4250 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 11:
1910 divided by 451 is 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 33424.594
The remainder is 106 after subtracting 1804 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
If we divide 1060 by 451, we get 2 and a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 33424.5942
The remainder is 158 after subtracting 902 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 13:
The number 451 fits into 1580 3 times, leaving a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 33424.59423
Subtract 1353 from 1580 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 14:
2270 divided by 451 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 33424.594235
Deduct 2255 from 2270 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
When dividing 150 by 451, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 33424.594235
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 16:
451 goes into 1500 3 times with a remainder of 147.
Write down 3 as next digit of the result. 
Result so far: 33424.59423503
If we subtract 1353 from 1500, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

In conclusion, the division gives 33424.59423503 with a balance of 1.47e-07.
